how much H2O2

I can't find this answer anywhere even though using h202 is discussed all over the place on forums. I was using a 35 gallon tote and couldn't stop algae even with using Hygrozyme, I figure it can only be b/c it wasn't light proof. I've now switched to bubble buckets and want to know how much 3% h202 I can use per gallon. I know it breaks down after a few days and you can add it like every 3 days or smaller amounts every day. This is not to cleanse the bucket and flush the system, it will be used with the plants in the buckets... It is compatible with the hygrozyme so that's not an issue.

Please, how much per gallon.... it's like it's a big freakin secret, everyone talks about using it but no one says how much....
